- L. G. HUNTINGTON WOQDWORKING MACHINE Filed Feb 2 1925 s sheets sheet 5 gwuehtoz Qua: W214 WQOZJWURK Application filed February This invention relates to new and useful improvements in woodworking machines, and particularly to machines for treating sash stiles.

One object of the invention is to provide aniachine by means of which a plurality of stiles may be simultaneously bored and plowed, to permit the attachment of the sash cords and to permit free passage of the sash cord pulley of the window fralne.

Another object is to provide a machine of this character wherein the stiles are fed from a hopper, singly, to an endless carrier for presentation to boring and plowing means, and by means of which every alternate stile is turned over as it passes from the hopper to the carrier, to provide for boring and plowing on the corresponding edge faces thereof.

Another object is to provide a machine of this character wherein an endless carrier is intermittentlyInoved forwardly a predetermined distance to position a number of styles before the boring and plowing nieans, simultaneously, and then to stop the carrier in such position, at which time the boring and plowing means are advanced to the stiles for action thereupon, the boring and plowing means being subsequently with drawn after completing their work, and the carrier moved to position the stiles before the boring and plowing means in a different order.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

Referring particularly to the accompanying drawings, there is shown a supporting frame or table which includes the legs 10, and the upper horizontal frame which coin prises the longer side bars 11 and the transverse bars 12. Mounted on the ends of the members 11 are the bearings 13 in which are rotatably supported the ends of the two transverse shafts 1e and 15, and mounted on these sl'iafts, at the ends thereof, are the sprocket wheels 16 and 17, the former being disposed. at one side of the table, while the latter are disposed at the other side thereof. Engaged around these sprockets are the chains 18 and 19, respectively, each of said chains carrying the conveyor lugs or flights 20, and each of the chains running through the channel members 21, 22, the former of which is fixed on the supporting frame, while the latter is adjustable toward and away from the former, as will be explained later herein. The sprocket wheels 17, and the channel 22 are supported by a yoke 23,and formed in the lower portion of this yoke are the internally threaded bosses 2%, through which are engaged the threaded adjusting rods fhe sprockets 17 are splined on the shafts L1 and 15, whereby they are permitted to slide longitudinally thereon, when the yolte is adjusted, and at the same time maintain their driving connection with said shafts. On corresponding ends of the threaded rods 25 there are fixed the sprocket wheels 26, and engaged around these sprocket wheels is the chain 27, whereby said rods will rotate in unison. On one of the rods 25, outwardly of the sprocket wheel a6, there is mounted a bevel gear 28, to which reference will be made later herein. Extending transversely of the support ing frame of the machine, and suitably supported in the sides thereof, is a shaft 30. On this shaft 80 are fixed the radial arms 37 and 42, the former of which engages a earn 33', on the shaft 33, while the latter are connected with the bars 43. At one end of the table is mounted a hopper 31. into which are forwardly the stiles will be carried thereby, to the other end of the table, and discharged therefrom.

In view of the fact that the stiles must be treated in pairs, it is necessa y to treat one edge face of one stile and the reverse taco of the next stile whereby to produce a pair of stiles for a single sash.

Extending longitudinally of the table, at one s de thereof, and mounted in sui able bearings 32, is a shaft and fixed on this shaft are the came 3% and S5. Properly supported on the table, and extending trans rersely thereofl in parallel relation to the rods 25, is a shaft 36, on which are secured the radial arms 31" and 42, the latter engaging; cam 36 and the former oeing connected with bars 38 by means of the links 38. hear one side of each of the channels.

' 21 and '22 is a longitudinally extending; bar

38, and pivotally connected at their lower ends to these bars are the series of vertically disposed stop members 39 the upper ends oi? which are ar ringed above the channel members for engagement with the opposite side faces oi? the stiles, from those engaged by the lugs 20. The intermediate portions ot the members 39 are pivotally mounted on the s des of the channel members 21 and E22 whereby, as the bars 38 are shifted longitudinally the stop members $39 will be rocked on their pivots into and out of engagement with the stiles. On one end 01 the shaft 'l-l; there is fixed a toothed wheel 4:0, which engages with a peripheral rib formed on the cam wheel 34c, said rib ncluding the porions ll which extend around the wheel in parallel relation and the transverse oblique portion tl extending letween and connwted to the portions ll. l l hen the oblique portion 41" ei'igagcs with the teeth of the wheel 4.0 said wheel will be rotated to turn the shaft 14, and thereby drive the chains to advancethe stiles to the tools. Vi hen the portion ll engages the wheel lO said. wheel re mains idle, with the remit that the chains 18 and 19 remain stationary for a sutlicient period to perinit action of the tools which will be later d scr bed, herein. The wheel 84 is in constant rotation, and at each revolntion thereof the oblique portion of the rib will turn the wheel to cause the chains 18 and 19 to advance a distance equal to the distance between an adjacent pair of lugs 20,. which is also the distance between the tools wh ch will be later described. Also ECCLHQCl to the shaft 30 1s a radial arm and pivotally connected with the outer end of the arm is one end of a rack bar 4-3. said bar being 'slidably supported adja ent the bottom of the hopper 31 and engaging with apawl and ratchet pinion l l loosely mounted on the short shaft carried by the side of the table. andjshownat 45. Onthe other end of this shaft 45 there is secured inter inittent gear all; which meshes with intermittent gear ll on a stub shaft ill mounted tlllOi'OlilC ehatlit 4-5. 011 the other end oi the stub shaft ell; there is s-ecnred the lltlllFiUllilll a stile within their biturcalions. l ivotally mounted on the incl: bar l?) are the rorti rally extending lllfi'fi Fl which swinn down. :n-a the bar mores ixi riuwardly beneath the hol tom of the hopper. and return to n nin ht posi lion to grip and pull a Fliilo .tron'i the hopoer to d. 10%? its ends in the bifurcated l 7 members lll and 53th when said bar nnwes ihjnsnfarilly. l hen a stile is properly on ed in the bi'l nrca" ted members i ll and L ii the raclt bar moves jtoiwvzirdly beneath hopper. the shalt i5 romaine stationary. lit when the earl; bar moves l' iill'ltltl'lll i the t is rotated and the billn'cntod nienibcl' d (1 rnod. lhron ijh the inediuin oi the nears J. i, and ill to overturn or rereiase the stile .i'or presentation to the low it) oi the con-- 'Yeyor chains in and ill.

The operations of moving}; the bite into the worln and then withdrawing some from the work take place during); the in terval when the portions -.l-Il oi the cam rib are n engagement with the wheel 40. and the chains 18 and 19 are stationary.

l idjacent the bracket 52 iii a bracket 59. the upper portion of which is liorined with a horizontal slidewny (it) which slidably supported the platform 61 of the motor 62. Carried by the platform 61, and extending forwardly and horizontally therefrom, over the adjacent chain 18, is an arm 68, which supports a gear casing (54, containing gears 65 which are operatively connected with the motor shaft and with the plowing or grooving tools 66 and 67. These tools 66 and 67 are spaced adistance apart equal to the dis tance between the stiles on the chains 18 and .19, so that said tools can simultaneously operate upon two alternate stiles. One of the tools is adapted to plow a long, comparatively narrow groove in the edge face of the stile, while the other tool is adapted to plow a comparatively wide and shorter groove, which extends longitudinally from the inner end of the wider groove. The inner end of the narrow groove terminates in the adjacent of the openings which are bored by the bits 56. In the lower face of the platform 61 there is formed a series of rack teeth 68, which is engaged by the mental gear 69 carried by theupper end of the bent lever 7 0 which is pivotally sup ported on the bracket 59, and has its lower end provided with spaced rollers 71 for straddling engagement with the peripheral flange of the cam or eccentric wheel 72 secured on the shaft 83. Thus, as the wheel 72 makes a complete revolution it actuates the segment 69 to cause the motor and the tools 66 and 67 to be advanced along the face of the stile, and to be withdrawn fro operative engagement therewith.

Also mounted on the side of the table, above the shaft 33, is a bracket 73 which has a downwardly and inwardly inclined slideway 7a, in which is slidably supported the platform 75. On this platform is mounted the motor 76, which is operatively connected with the obliquely extending boring bit 77, said bit being arranged to bore an opening which connects the two openings bored by the bits 56, and through which the sash cord, not shown, is arranged to be passed, a knot being made on the end of the cord and seated in one of the pair of openings.

On the lower face of the platform 75 there is formed a toothed rack 78, which is engaged by the segment 7 9, on the centrally pivoted arm 80, which is mounted on the bracket 73. The lower end of the arm is provided with a pair of rollers 81 which straddle the peripheral flange 82, of the eccentric or cam wheel 83, which is mounted on the shaft 33. Rocking of the arm 80 causes the platform to be moved forwardly and rearwardly to advance the bit 77 into working relation to the stile, and to with draw same therefrom, after proper action upon the stile.

Splined onthe shaft 33 is a sleeve 84, on the opposite ends of which are formed. the

bevel gears 85 and 86, suitable means 87 be-- ing provided for shifting this sleeve on the shaft to engage one or the other of the gears 85-86 with the gear 2-8, whereby to car se sired direction for the purpose of moving the chain 19, and the mechanism associated therewith, toward and away from the chain 18, to accommodate stiles of different lengths.

From the foregoing it will be seen that there has been provided a machine wherein stiles are fed, singly, to an endless conveyor which carries the stiles int positions oppo site a series of boring and plowing devices. Also, mechanism is provided which moves the conveyor in a step-by-step fashion, so that the stiles will be stopped and held in their positions opposite the tools, for a sufficient period of time to permit the tools to perform their work on the stiles. Thus, while one stile is being formed with two holes bythe pair of bits 56, the stile which is two spaces ahead is being formed with a narrow groove, while the stile two spaces ahead of the last-named stile is being formed with a wider groove. The foremost stile is being formed with an oblique opening which connects the openings formed by the pair of bits 56. Thus the operations of boring and plowing are being performed simultaneously upon a plurality of stiles, and when the most advanced stile is discharged from the machine it is properly provided with grooves and openings for the reception and attachment of a sash cord.

Furthermore, every other one of the stiles,

as it is automatically moved from the hopper, is overturned into a position to permit its other edge face to be acted upon by the tools, so that it forms a companion stile for either the one which precedes or follows it. Also, the pivot-ed stop arms 39 cooperate with the lugs 20 to hold the stiles while being acted upon by the tools, such stops being immediately released to permit the carrier to be advanced one space for the next operations.
